Comparing 304 and 316 Stainless Steel

While both 304 and 316 stainless steels are popular austenitic grades, they have some key differences:

  1. Composition: 316 contains 2-3% molybdenum, which 304 lacks
  2. Corrosion resistance: 316 offers better resistance to chlorides and acids
  3. Cost: 304 is generally less expensive than 316
  4. Applications: 304 is more common in general-purpose uses, while 316 is preferred for marine environments
  5. Strength: Both have similar mechanical properties, but 316 has slightly higher strength at elevated temperatures

Choosing between 304 and 316 depends on the specific application requirements and environmental conditions.
